Thyroid cancers
The most common carcinomas that originate in the thyroid tissue
Epi: Frequency of 80 percent (most common); good prognosis (10 year survival 95%); F:M 3:1; peak incidence in 30s to 50s
Gross: irregular contours, no capsule around it
Histo: nuclear clearing (nuclei appear empty - “Orphan Annie eye†), nuclear grooves, intranuclear pseudoinclusions, psammoma bodies (calcifications) , reduced colloid, crowded cells, papillary architecture (sometimes present)
Derived from follicular cells
Increased risk: mutations (RET and BRAF), radiation exposure as child
Spread: often by lymphatic invasion to cervical nodes, neck; slow growth
Secretes thyroglobulin; takes up radioiodine
Treat: lobectomy (maybe total thyroidectomy with lymph node removal)
High risk pts get radioiodine tx
TSH suppression with thyroid hormone replacement
Epi: Frequency of 10 percent; more aggressive than papillary with early metastases; also F:M 3:1; peak in 40s to 60s
Histo: monotonous/uniform population, overlapping follicular cells, microacinar formation, reduced colloid, might contain Hurthle cells
Derived from follicular cells
Increased risk: mutations in RAS
Spread: often by vascular invasion; locally invasive, invades thyroid capsule
Distal spread more common than papillary
Invades blood vessels and invades through the capsule
Differentiate from follicular adenoma:
Secretes thyroglobulin; takes up radioiodine (except Hurthle cells)
Same treatment: lobectomy (maybe total thyroidectomy with lymph node removal)
High risk pts get radioiodine tx
TSH suppression with thyroid hormone replacement
Epi: Frequency of 5%; more aggressive than follicular with early metastases;
Sporadic (80%) → F:M 3:2, peak in 40s to 60s
Familial (20%) → F:M 1:1, peak onset at early age
Histo: neuroendocrine appearance, ‘packets’ of uniform cells; stroma made of amyloid (stains w Congo red)
Derived from parafollicular cells (C (clear) cells); produces calcitonin
Increased risk: family with MEN 2A and 2B (association), mutation in RET (proto-oncogene)
Spread: early metastases
Does not secrete thyroglobulin; does not take up radioiodine
Same treatment: lobectomy (maybe total thyroidectomy w lymph node removal)
Thyroid hormone replacement for normal TSH (no TSH suppression)
Anaplastic carcinoma
Left of image is amyloid, right of image is near normal thyroid follicles
Anaplastic carcinoma
AKA undifferentiated carcinoma (because it’s poorly differentiated)
Epi: Frequency of 3 percent; very aggressive, poor prognosis, most deadly; M:F 2:1, peak in 60s to 80s
Histo: several variants, but all high grade
Spread: infiltrative into local structures, soft tissue of neck; widespread metastases, early mortality
Does not take up radioiodine
Papillary carcinoma
Follicular carcinoma
Medullary carcinoma
Anaplastic carcinoma
Up to the point and very clear. Thank you 👏👏🦮
Amazing work. Thank you.
My symptoms of follicular thyroid cancer was a nodule on my thyroid my first doctor I went to told me I had a nodule and I need to come back in a year and get rechecked. The second doctor I went to a week later told me I needed to get into surgery ASAP and get a biopsy which led to a total thyroid ectomy a month later please don't mess around with a doctor who says they want to wait
You are wise.
Don't ever change.
Thanks so much!
Thank you for the good explaination
Thank YOU,great explanation 🙏🏼🙏🏼🙏🏼
Thank you 🙏🏻
Thnx , good , simple and important points ,
thankyou so much
ty. short, sweet, high yield
Don't mess around with a doctor who says they want to wait and watch it grow that is exactly what happened to me. It might have been because I was low income. Because I got married after I went to the first doctor that told me to wait when I got married the man I married had good insurance and I went to a different doctor that told me I needed to get a biopsy which led to my diagnosis but my first doctor I went to when I had no insurance told me to wait and we will get a recheck in a year please don't wait please don't let a doctor dictate your Life Path
you are right, i have the same case, went to another doctor with all my lab test results fr my previous dr, i underwent to another biopsy to recheck ang advice me to undergo surgery, but my dr before told me i dont have to worry about the delay in which my husband disagree,
Here iam now after my surgery 2 mos later.iam still lucky that the cancer cells didnt pooped out, i got the lazy one, if i waited more, maybe it will become worst
I loved it but would like if there was more pictures. :)
Right, do they all create a lump or do the other 2 present itself differently?
They all present with a lump/nodule in the neck.
Pathology would be different for each.
@@Shalondria what if the doctor says its just a cyst? I've met 2 people recently both having that condition. One had her thyroid removed, the other was told to wait. Thank you.
❤️❤️❤️
🙏🌷
And just to let you know when I had follicular thyroid cancer I was 23 years old this video says you need to be in your 40s so please keep a idea in your head that I was in my early twenties and doctors don't want to think young people have cancer
You’re good buddy I’ll give you credit, but you need to SLOW down a little bit I don’t know, but you explain everything very fast.. and please keep the amazing work up
Slow down the speed. Problem solved.
@@revelations2798 lmao I’ve graduated already but you cracked me up you’re right 😂😂
Fucking awesome video
few week ago I felt some pains and I went to the hospital my doc told me I had Herpes about 1 yr and I need to start the treatment early from DR OIGIANGBE 💯
Crack 👌🏼

my understanding was that anaplastic carcinoma is more common in women?
Otherwise
Would you talk about the symptoms please?
Your product for eradicating herpes is actually the best DR OIGIANGBE on RUclips. I am herpes negative now keep the good work sir.
